Very, very, very unlikely that you're pregnant. The morning after pill would have sorted the issue, and even before that the likelihood of you being pregnant is pretty much zero.

Your periods will be delayed/irregular for a month or two since the morning after pill will affect it, and stress will affect it too, so don't worry if it doesn't come on time.

If you're going to be having regular sexual relations, have you considered birth control? It might be beneficial for you to look into it and pick one that suits you. That way you will be protected from pregnancy.
